Application filed October 20, 1913. Serial No. 796,272.

To all whom it may concern:

Be it known that I, KARL EARTH, residing at Essen-on-the-Ruhr, Germany, a subject of the Emperor of Germany, have invented a certain new and useful Improvement in Self-Unloading Vessels, of which the following is a specification.

This invention relates to self-unloading vessels wherein the receptacle holding the loaded goods is given rectangular cross section when in loading positlon, and which receptacle when transferred 1nto discharging position changes its rectangular shape, so

is illustrated in the drawing representing a self-unloading car and Figure 1 shows a cross section of the car in the loaded position and Fig. 2 a view similar to Fig. 1 of the car in unloading position.

The two end walls A are rigidly secured on the bottom frame A of the car, and these walls are reinforced at their corners bytwo rods a and a parallel to the longitudinal axis of the car. unloading car is, by means of a shaft 1), revolubly mounted in bearings in the" end walls A and this shaft is situatedon the hinged connection with the bottom B and is at its upper end provided with rails 0 which are guided on suitable rollers. a

mounted on the rod a The rails c are bent yarrow a, see-Fig. 2, unt l the sidewall C at their upper ends, into hooks c with which they engage the rollers an in the load-.

ing position of the car, see Fig.1, so that the bottom B- is secured against turning in the direction of thearrow w. The opposite side wall C is hinged to-the rod a and is provided with hooks 0 at its lower end,;

.tlOIl. whenin loadlng position, said recepwhich hooks grip under the bottom Bland hold it in the. loadingposition as illustrated in Fig. -1. In dischargingposition shown in 'Fig. 2,-the bottom B rests on a beam a secured on the bottom frame 'A'of the car. 1 A

-crank connection with a hand lever fD, is

linked tothe side wall C, which is intended The bottom B of the self-.

. B returns to its original loading position, Fig. 1, from its discharging position, Fig. 2, assisted by the weight of the side wall C either to lock the side wall in its loading position, or to swing it around its rodo When the car is to beunloaded the hand lever D is turned in the direction of the arrow y, see Fig. 1, so that the side wall C 1s swung outward and the hooks 0 disengage from the bottom B. As soon as this has taken place the weight of the loaded material will tip the bottom B in the opposite direction to that of the arrow 00, in consequence of the shaft 5 being situated to one side of the car, and this tipping of the bottom continues until the bottom is stopped by the beam a The side wall C, hinged to the bottom B, will as a consequence of this jmovement be raised, while the rails c are sliding on the rollers a The anglebetween the side wall and the bottom B will simultaneously grow larger, whereby the. original rectangular shape of the car receptacle will be changed. This condition makes it possible for packed material, such as clay, to be automatically unloaded, asv on account of the change of the rectangular cross section of the car receptacle the adhesion, as

well as the cohesion of the loaded material will be considerably diminished. The auto- .matic unloading will-be still more augment ,ed through the shaking of the material Icaused by the dropping of the bottom B against the beamoP. 5

At the end ofthe discharge, the bottom has arrived in the position shown in Fig.

1, when the hooks c engage under the body B. r 7
